To report spam or commercial iMessages, you can use the Report Junk link in Messages, or send an email to Apple. iMessages are blue and say "iMessage" in the conversation thread. Learn more about the difference between SMS/MMS and iMessages.
To report report SMS and MMS messages, contact your carrier.
Report an iMessage as junk in Messages
In iOS 8.3 and later, you'll see a Report Junk link when you get an iMessage from someone who's not saved in your contacts. This will send the sender's information and message content to Apple.
Report an iMessage by sending an email
If you don't have iOS 8.3 or later, you can send an email to firstname.lastname@example.org with this information:
- A screenshot of the message (See how to take a screenshot on your iPhone, iPad, iPod touch, or Mac.)
- The email address or phone number that sent the iMessage
- The date and time that you got the iMessage
